Ring main unit

Xgn15-12 modular sulfur hexafluoride ring main unit (SF6) is a new generation of high voltage switch cabinet, which uses SF6 switch as the main switch and air insulation as the whole cabinet. It is suitable for distribution automation and is compact and expandable. Because the ring main unit uses SF6 load switch, it is also called SF6 load switch cabinet / SF6 switch cabinet, which is composed of control room, bus room and cable room. The SF6 load switch operating mechanism installed in the control room can control the circuit breaking through the operating mechanism. At the same time, five prevention interlocking is installed to prevent misoperation from causing safety accidents. SF6 load switch is installed in the bus room and connected with other ring main unit through copper bar. The lower part of the cabinet is the cable room, which can be assembled with grounding knife, primary fuse, lightning arrester, voltage transformer and other components according to the customer's requirements. At the same time, the cable hole is reserved, and the cable is connected into the cabinet from the lower end。

advantage

1. It has the advantages of simple structure, reasonable layout, safe use and easy maintenance.

2. It can limit the amplitude and time of short circuit current.

3. It can protect transformer reliably and effectively.

4. It has the function of isolating switch and can be installed with grounding switch.

5. Advanced computer aided design improves the standard of product structure and size.

purpose

Xgn15-12 type SF6 ring network cabinet is suitable for AC 50 Hz, 12 kV power system, widely used in industrial and civil cable ring network and power supply terminal project. It is often used in city residential area distribution, small two substations, opening and closing offices, industrial and mining enterprises, shopping malls, airports, subway, wind power, stadium, railways, tunnels, etc.

Fully enclosed SF6 load switch

The main switch of the ring main unit adopts the fully enclosed SF6 load switch as the main switch, which is convenient for installation and maintenance, insulation arc extinguishing and main protection主开关不易生锈腐蚀，使用寿命可达30年。

Safer with operating mechanism

The main switch of high voltage ring network cabinet is controlled and disconnected by SF6 load switch operating mechanism. Manual or electric operation can be selected, and five prevention interlock is provided at the same time, which is more safe and reliable.配五防联锁，更加安全、可靠。

Double protection with high voltage fuse

The high-voltage fuse is used to connect the high-voltage ring main unit's incoming end with the cable, and the ceramic fusible core holder is used for better insulation performance好，可防止短路损坏设备。

Add all kinds of accessories as required

Enough space is reserved in the cable room of the voltage ring network cabinet to facilitate cable connection. At the same time, high voltage arrester, voltage transformer, zero sequence transformer, heating plate and lighting lamp can be added according to different customer needs

hy liwang ring main unit is so trusted

Why do we trust it?

工艺优美

: Liwang electric strictly treats every detail, pursues the beauty of the product while ensuring the quality, and requires that the process and routing of the primary and secondary lines be unified and standardized, in line with the public aesthetic。

走线生硬

: Considering the cost of wiring products in the market, we can save the auxiliary materials such as wires. The process is not in line with the public aesthetic. At the same time, it is easy to leave quality hidden trouble and inconvenient for maintenance修。

原装正品

: All the auxiliary materials of liwang electric, such as miniature circuit breakers, wires, surge protective devices, copper bars, etc., are selected from domestic well-known brands with original authentic products to ensure that every component is high-quality and authentic raw materials！

杂牌假货

: The choice of auxiliary materials and brands of products in the market is uneven. Many of them only consider the cost of choosing minority brand materials, and even use counterfeit goods, which makes customers mistakenly think that they are genuine products and seriously infringe on the rights and interests of others!益！

美观稳固

: The shell of Liwang Electric's high and low voltage switch cabinet is made of high-quality aluminum zinc coated plate, with a thickness of 1.5mm. The shell is more solid and stable than the cold-rolled plate, with good corrosion resistance and heat resistance, and the paint is not easy to fade.色。

质软易腐

: In order to save cost, some enterprises in the market choose cold-rolled plate as the shell. The stability of the cabinet is not enough, and it is easy to shake. It is easy to rust after 2-3 years of use, and the painting is not smooth, and it is easy to fall off.漆。

加量不加价

: All high voltage ring network cabinets of liwang electric are equipped with heating plates and lighting lamps in the cable room to facilitate maintenance and keep the room dry, prevent corrosion and prolong service life.

容易受潮

: Most of the products in the market are not equipped with heating plates and lighting lamps, which will cause inconvenience to the later equipment maintenance. If the equipment is located in a humid environment, the cabinet and related components are easy to be corroded, greatly shortening the service life.
